I have run a few cylinder tests using AE and it seems like a few of my injectors might be weak/bad. I also think I have a slight miss, which is hopefully just a bad injector. I assume I don't have the knowledge or skills to check in injectors myself, so what should I do? Send the to someone to be check out, if so who. Also is this going to be a very expensive process, am I better off getting new injectors? Thanks guys.

Cylinder Contribution Test. The MMs have been in for over 2 years, I bought them used but put on new o-rings and all that. I have had the miss for a while, but it drives just as well as it always had. I finally did the AE test after reading about someone else using AE to figure out their miss. When I did the test no cylinder was more than 2.3% (usually these were less than 2%), some were 0%. I can't remember which cylinders exactly, I'll have to run the test again. I read on the ITP website than only be very worried if any cylinder read constantly over 3%, and none of mine did.

I assume you are taking about the Cylinder contribution test on AE, or possibly reading the cylinder rotational velocity in the live data graph. What were the results / numbers?

As a possibility, have you have replaced your CPS recently with the new one that Ford came out with during the recall? Quite a few folks have noticed increased numbers on the cylinder rotational velocity readings compared to the readings with the old CPS.

Well, you answered one of my questions before my slow but finished typing. Your injectors seem fine with those numbers. How about the CPS?

Thanks for the info guys, nope i have not changed my CPS. I will run the test again tomorrow and let you guys know exactly what the max numbers are. What/where exactly UVC harness? Is that the connection on the valve cover?
